Definitions
- This invention relates to an image forming method applied to an image forming apparatus, such as a digital copier, having not only a copying function but also a facsimile function or a printer function.
- the digital copier has a scanner, printer, memory, image processing section, etc.
- the scanner optically reads out a document and converts its image to an electric signal.
- the image processing section applies a variety of image processing to an image data read out by the scanner.
- the memory accumulates the image data to which the image processing is applied by an image processing section.
- the printer subjects the image data which is stored in the memory to a laser electrophotographic process to form an image.
- the digital copier thus configured can realize not only a copying function equal to that of an analog copier but also a facsimile transmitting function, facsimile receiving function and printer function.
- the facsimile transmitting function and facsimile receiving function are realized by having a facsimile communication section connected to a public network.
- the facsimile transmitting function allows a document image to be read out by a scanner and the image to be transmitted by the facsimile communication section through the public network.
- the facsimile receiving function allows the image which is transmitted by the facsimile communication section through the public network to be received and the received image to be printed by a printer.
- the printer function is realized by having an image communication means relative to a host computer as an external apparatus.
- the printer function allows the print data to be received by the image communication means and the received print data to be printed.
- the digital copier has a memory for storing the image. It is therefore, not necessarily required that the scanner and printer be operated in a synchronized relation as in an analog copier.
- the digital copier transmits the image which is read out by the scanner.
- the digital copier can print, by a printer, the print data received by the print communication section from an external apparatus.
- the digital copier enables the scanner and printer to execute separate types of processing (jobs). That is, the digital copier can perform “multifunction operations” by which a plurality of processing are done simultaneously.
- the digital copier having a memory, does not require a complete synchronization operation as in the case of the analog copier. That is, even if the printing of the image is not executed at a time of inputting the image, printing can be executed after the image has been stored in the memory. In this way, the operation condition under which the image inputting processing and image printing processing are separately operated is called a “completed type”. In the copy processing of the “completed type”, all the document image is scanned by the scanner. The image thus scanned by the scanner is stored in the memory.
- the printer prints images sequentially read out from the memory.
- the digital copier can effect the inputting of the image and printing of the input image in a synchronized way.
- the operation condition under which the image inputting processing and image printing processing are done in a synchronized way is called a “sequential type”.
- This “sequential type” speeds up a time of starting the print of the image when being compared with the “completed type”.
- the “sequential type” operation condition is used.
- the “sequential type” copy processing performs, in parallel with the scan processing of the image by the scanner, print processing of the scanned image.
- Some scanner used in the digital copier has an auto-document feeder (ADF) for feeding a plurality of documents sequentially to a scanning position.
- ADF auto-document feeder
- Some digital copier has a mode (usually, a single-sided/single-sided operation mode) in which it sequentially reads out the single side surface of the document with the use of the ADF and effects a printing on a single side surface of a copy sheet.
- the scan processing of the document by the scanner and print processing of the image by the printer are done in a synchronized relation. By doing so, a better productive operation is realized in a shorter time from the starting of scanning to the completion of printing.
- the scanner and printer are occupied under one copy processing while performing at least a scan operation. During the execution of the “sequential type” copy processing, therefore, the scanner- or printer-utilizing processing cannot be done in a parallel operation.
- a copy operation is effected during the printing of the received print data.
- a copy operation is effected during the printing of the received facsimile document.
- One control method is by giving a priority to the copy processing.
- the processing done by the printer is once stopped at a time of starting an operation of copy processing.
- the copy processing is implemented in the “sequential type” mode.
- a state is set in which the next processing can be done.
- the interrupted printing of the received data is resumed.
- the scanner and printer are occupied by the copy processing during a predetermined time from the starting of the operation by the user to the termination of the copy processing.
- the printer takes more practical inoperative time and more loss time. Further, since the processing now performed for the copy processing is stopped and resumed, complex control is involved.
- the second control method is by giving a sequential priority to a print request. Even if the copy processing is designated, this control method gives a sequential priority order in which a request for the processing by the printer occurs.
- the processing is performed in the “completed type” mode.
- the copy processing is such as to separately performed the scan processing by the scanner and print processing by the printer. That is, the copy processing is done by first performing document scan processing by the scanner. All document images read out by the scan processing are stored in the memory. When the scan processing is completed, a request is made for the printer to perform the print processing on the image stored in the memory. In this case where there are any processing executed by the printer and any processing now waiting for printing, the print request is such as to start the print processing of the copy processing after these of processing has been completed.
- the copying processing becomes at all times a “completed type” operation. Even if, therefore, the copy processing is independently implemented, there arises the problem that the copy processing is made lower in productivity. If there are a plurality of processing waiting for printing, printing is started after these of print processing are all completed. In the case where, therefore, many of processing wait for printing, there arises a problem that the printing start of the copy processing is delayed.
- the image forming apparatus poses a problem that it has to adopt any one of a first operation condition under which it is not possible to perform a parallel operation during image formation but it is possible to achieve a higher productivity and a second operation condition under which it is possible to perform the parallel operation during the image formation but it is not possible to achieve any higher productivity.
- the present invention is achieved according to which a parallel operation can be realized without lowering that productivity.

- Another image forming method of the present invention applied to an image forming apparatus having image inputting means for inputting image data and a printer for forming the image data on an image forming body, the method comprising the steps of, judging whether or not, at a start of image forming processing on image data inputted by the image inputting means, the printer perform any other processing; when it is judged that the printer performs no other processing, setting a first operation condition or second operation condition in accordance with processing contents of the image forming processing, the first operation condition being a condition under which image data as an object of the image forming processing is sequentially inputted by the image inputting means and image forming processing is performed on the image data sequentially inputted by the printer and the second condition being a condition under which, after inputting all image data as an object of the image forming processing by the image inputting means and storing the image data in the memory, the image forming processing is performed by the printer on the image data stored in the memory; when it is judged that the printer performs any other processing, setting the operation condition of the image

- first operation condition is the operation condition under which a plurality of resources, such as the scanner section 2 and printer section 3 , are operated in a synchronous way.
- a plurality of resources such as the scanner section 2 and printer section 3
- an operation is done with the scanner section 2 and printer section 3 shychronized as shown in FIG. 2 .
- a first page printing is started at a time point when a document image corresponding to the first page is read out by the scanner section 2 as the image inputting means.

If, for example, the copy processing is done under the “completed type” condition, the scanner section 2 and printer section 3 are operated in a nonsynchronous way.
- the copy processing under the “completed type” operation condition is such that, after the completion of the reading of images of all document page sheets by the scanner section 2 as the image inputting means, the image of the first page starts to be printed.
- the scanner section 2 and printer section 3 are not simultaneously occupied during the performing of the copy processing.
- the printer section 3 can perform the printing of an image in other than the copy processing.
- the processing operation condition can be set by being selected from the “sequential type” and “completed type” operations.
- a printing job request is made for the printer section 3 , unless there is any printing job in the printing queue 23 a , the printing job is operated independently. In this case, the printing job is performed based on the decided operation condition and in accordance with the processing content.
- the operation condition is determined in accordance with the operation situation of the printer section 3 .
- the operation condition of the copy processing is the “sequential type”. If, in this case, upon the performance of the copy processing, the printer section 3 performs any other processing, the operation condition of the copy processing is changed to the “completed type”.
- the operation condition of the processing can be changed in accordance with the operation situation of the printer section. By doing so it is possible to effect control under which the printer section can be most efficiently operated.
- the user sets the copy processing condition on the operation panel 4 .
- the user depresses the start key 52 .
- the main CPU 11 judges from a signal from the panel CPU 51 that the start key 52 was depressed (step S 1 ).
- the main CPU 11 checks the setting condition of the copy processing (step S 2 ).
- the main CPU 11 decides the operation condition of the copy processing on the basis of the setting condition of the copy processing.
- the operation condition of the copy processing is such as to decide any of the “sequential type” operation or “completed type” operation.
- the main CPU 11 decides the operation condition of the copy processing as being a “sequential type” operation.
- the main CPU 11 Based on a result of decision, the main CPU 11 prepares a copying job where the operation condition flag as to whether the sequential type or completed type is involved is set (step S 3 ).
- the main CPU 11 checks the printing queue 23 a (step S 4 ). By this checking, the main CPU 11 judges whether or not a job is already present in the printing queue 23 a (step S 5 ). If, here, there is a job in the printing queue 23 a , a job registered at the highest position of the printing queue 23 a is now being performed. That is, if the job is present in the printing queue 23 a , the printer section 3 is in a state occupied by the now performing job.
- the main CPU 11 changes the operation condition flag of the copying job to the “completed type” (step S 6 ). Therefore, in the case where, at step S 3 above, the operation condition flag of the copying job is set to the “sequential type”, the operation condition flag is changed to the “completed type”.
- step S 7 If, at step S 5 above, it is judged that there is no other job in the printing queue 23 a , the main CPU 11 starts a copying job on the basis of the set operation condition (step S 7 ). If, at step S 6 above, the operation condition flag of the copying job is changed to the “completed type”, the main CPU 11 starts the copying job under the completed type condition (step S 7 ).
- the main CPU 11 checks the operation condition flag of the copying job (step S 8 ).
- the main CPU 11 judges whether or not the operation condition flag of the copying job is the “completed type” (step S 9 ).
- step S 10 If it is judged that the operation condition is the “completed type”, the main CPU 11 performs a copying job under the “completed type” (step S 10 ). If it is judged that the operation condition flag is not the “completed type”, that is, the operation condition is the “sequential type”, the main CPU 11 performs the copying job under the sequential type (step S 11 ).
- the operation condition of the copying job is the “completed type”. According to whether or not there is any processing during printing or at a printing wait time, the operation condition can be set so as to allow the scanner section and printer section to be operated efficiently.
- the main CPU 11 starts scan processing under the copying job (step S 21 ). Those images read out by the scan processing are formed as an image file and sequentially stored in the image file memory 17 (step S 22 ). By doing so, when the images of all pages are stored in the image file memory 17 , the main CPU 11 completes scan processing under the copying job (step S 23 ).
- a print processing request is made for the copying job.
- the main CPU 11 sets the copying job to the printing queue 23 a (step S 24 ).
- the main CPU 11 judges whether or not any copying job is present in the printing queue 23 a . If it is judged that the copying job is present, the copying job is preferentially taken out from the printing queue 23 a as the next job (step S 26 ). When the copying job is taken out from the printing queue 23 a , the main CPU 11 starts the print processing under the copying job (step S 27 ). By doing so, the images accumulated in the image file memory 17 are sequentially read out and print-processed by the printer section 3 .
- the operation condition of the copy processing is changed to the completed type so as not to prevent the operation of the printer section.
- the scanner section and printer section can be smoothly operated without lowering the productivity at a time of the copy processing.
- the operation condition of the copy processing is changed to the completed type and, when the printer section ends the now performing processing, the printing of the copy processing is performed in preference to the processing now waiting for printing.
- the printing queue 23 a allows various practical arrangements. For example, those jobs for which a printing request is made are sequentially registered in the printing queue 23 a . In this case, when the job is taken out, it is judged whether or not any priority job from the printing queue 23 a is present. If it is judged that the priority job is present, the priority job is preferentially taken out. If any priority job is not present, the jobs are taken out in the order of their being registered.
- FIGS. 6, 7 and 8 are views for explaining the cases where the jobs present in the printing queue 23 a are rearranged in a copying job preferential order.
- the main CPU 11 checks each job in the printing queue 23 a . By doing so if it is found that those jobs present in the printing queue 23 a are printing jobs, then as shown in FIG. 8, the main CPU 11 rearranges the copying job so as to locate it at the next position of a new performing printing job.
- the new copying job is rearranged such that it is preferentially performed after the currently performing job.
- the jobs involved are taken out at all times in a registered order.
- the jobs registered in the printing queue are preferentially rearranged each time a new job is requested. By doing so, the jobs can be performed in an order present in the printing queue.
- FIGS. 9 and 10 show the case of dividing the printing queue 23 a into a first printing queue 23 b and second printing queue 23 c .
- a preferentially performing copying job is registered in the first printing queue 23 b and any other job not given a priority in particular is registered in the second printing queue 23 c .
- FIG. 9 for example, let it be assumed that a plurality of printing jobs are registered in the printing queue 23 c . If, in this state, any job for printing occurs due to the copying job, the main CPU 11 registers the copying job in the printing queue 23 b .
- the job registered in the printing queue 23 b is preferentially performed when a job now being performed is ended.
- the main CPU 11 judges whether or not there is any job in the printing queue 23 b .
- the main CPU 11 performs the registered job in the printing queue 23 b .
- the main CPU 11 performs jobs registered in the printing queue 23 c sequentially.
- the printing queue is provided in which a preferentially performing job is registered and, when any job is taken out, the job is taken out preferentially from the printing queue in which the preferentially performing job is registered.
- any preferentially performing job can be registered in a printing queue other than that for any other jobs and it is possible to readily control the registering, taking out, etc., of the preferentially performing job.
